Justice for Nobita

0 have signed. Let’s get to 100!

All his life, poor Nobita has struggled to score marks in class tests. But the one instance where he solved the problem correctly, his teacher Sensei didn't give two f*cks about his answer and just marked it wrong as usual before awarding him the regular "zero". We're all here to demand justice for Nobita and bring his score above zero for the first time in life.

What else is supposed to be the answer for for equation 2 + ( 2 * 5 ) if not 12 ?
